    An Integrated Remote Sensing Drought Monitoring Model Based on Multi-source Information by Dejun ZHANG, Guan HONG, Shiqi YANG, Hao ZHU

    Published 2024-12-01
    “…In order to solve the problem of the traditional remote sensing drought index focuses on the monitoring of a single response factor and lacks a complete analysis of drought.In this paper, we selected TVDI, RVI, PDI, and GVMI daily products estimated from remote sensing data as independent variables, and MCI calculated from meteorological data at the adjacent moments of satellite transit as dependent variables, and uses the Random Forest Regression (RFR) model to construct a integrated remote sensing drought monitoring model.The results show that the accuracy of RFR model is better than that of the Ordinary Least Squares (OLS) model in bothtraining data and test data.The R value of the RFR training data is 0.97, the RMSE is 0.33, the R value of the RFR test data is 0.90, and the RMSE is 0.53.The R value of the OLS training data is 0.78, the RMSE value is 0.73, the R value of the OLS test data is 0.76, and the RMSE value is 0.79.The comparisons of RFR and OLS model in R and RMSE show that the RFR model is superior than the OLS model in the characterization of regional drought.In the application of drought monitoring in Southwest China in 2022, the RFR results are consistent with the spatiotemporal distribution of the MCI index, which can better characterize the spatial and temporal dynamics of the regional drought, reflecting the practicality of the RFR model in the actual drought monitoring process.However, the accuracy of RFR model is related to the number of regional stations and the spatial distribution of stations, and the accuracy of the RFR model is higher in areas with a large number of stations and uniform distribution of stations.…”

    Exploration of the Main Models and Optimization Paths for the Market-Oriented Operation of Urban Parks by Yanting LI, Qiaowan YANG

    Published 2025-06-01
    “…The institutional bottlenecks and implementation difficulties of the existing operation models are systematically analyzed. The current dilemma of balancing the public welfare and commercial aspects of parks as a public product is put forward together with the difficulties involved in park management, such as the complexity of cross-departmental coordination, and the lack of detailed policy basis and effective profit distribution system.ResultsBy constructing an “all-in-one map” of spatio-temporal park assets to achieve three-dimensional quantification of spatial assets, an inventory of the land, buildings, and facilities within parks is conducted, park plan is spatially classified, and in combination with the demand for mixed land use featuring the combination of dominance by public welfare and flexible compatibility”, park space is divided into core conservation areas, compatible utilization areas, and market revitalization areas. …”

    Simulation and Prediction of Spring Snow Cover in Northern Hemisphere by CMIP6 Model by Xulei WANG, Hui SUN, Hui GUO, Chula SA, Fanhao MENG, Min LUO

    Published 2024-12-01
    “…As one of the most sensitive natural elements in response to climate change, snow cover has a significant effect on the Earth's surface radiation balance and water cycle.The global snow cover area is approximately 46×106 km2 and 98% of the snow cover distributed in the Northern Hemisphere.Due to its distinctive radiative properties (high surface albedo) and thermal characteristics (low thermal conductivity), changes in snow cover play a crucial role in the energy balance and water cycle between land and the atmosphere.In the context of global warming, the snow cover in the Northern Hemisphere has been decreasing in recent decades, especially in the spring.Therefore, the capabilities of CMIP6 (Coupled Model Intercomparison Project Phase 6) data to simulate the snow cover area were evaluated based on observational data and the future changes in snow cover were also assessed using a multi-model average in this study.By using the snow cover products from the National Oceanic and Atmospheric Administration/National Climatic Data Center (NOAA/NCDC) as reference data, the Taylor skill scoring, relative deviation, and other methods were applied to evaluate the spring snow cover (SCF) data in the Northern Hemisphere from the International Coupled Model Comparison Project Phase 6 (CMIP6) during 1982 -2014.The ensemble average of the top three models was further selected to predict the spatiotemporal variation characteristics of SCF under different emission scenarios from 2015 to 2099, providing insights into the modeling capabilities of CMIP6 and future changes in SCF.During the historical period (1982 -2014), SCF was characterized by high coverage at high latitudes and low coverage at low latitudes, with high-altitude regions such as Tibetan Plateau and eastern Asia having higher snow coverage than those at the same latitudes.Overall, 68.37% of the regions in the Northern Hemisphere showed a decreasing trend in SCF, while 31.63% of the regions showed an increasing trend in SCF.Most CMIP6 models overestimated SCF in the Tibetan Plateau region compared to the reference data.In addition, most models simulated larger areas with a decreasing trend in SCF than those evaluated by the reference data and underestimated SCF in March, April, and May.Various models exhibited differing abilities to simulate SCF, with NorESM2-MM, CESM2, BBC-CSM2-MR, NorESM2-LM, and CESM2-WACCM demonstrating superior capabilities.The Multi-Model Ensemble Mean (MME) consistently outperformed individual models, closely aligning with observational data.There were significant differences in the ability of the CMIP6 models to simulate the spatial distribution, inter-annual variation trends, and intra-annual variations of SCF in the Northern Hemisphere.At the end of the 21st-century (2067 -2099), SCF in the Northern Hemisphere exhibited a decreasing trend in most areas, which intensifies with increasing emission intensity.The changes in SCF were relatively consistent under different emission scenarios before 2040.SCF maintains a steady state under the SSP1-2.6 scenario, showed a slight decreasing trend under the SSP2-4.5 scenario, and showed a significant decreasing trend under the SSP5-8.5 scenario after 2040.…”
